`This invention .i relates mechanism. y

This'invention` has utility when incorpo rated in connectioniwith a piston reciprocable in a cylinder, especially in internal combustion motors.y Y

Referring to the drawings:

section on the `line II-II,

The housing 1 is water-jacketed to inclose the cylinders 2 provided with an intake port 3 and an outlet or exhaust port 4 for each cylinder. Reciprocable in each cylinder `is a piston 5 having the lateral gridded port 6, the way from which extends out of the end of the piston 5 to open into the chamber of the cylinder. Centrally connected to each piston by a spherical bearing 7 is a connecting rod 8 extending to the crank shaft 9. In the operation of-this device as an internal combustion motor, the reciprocation of the piston 5 in this cylinder will operate through the connecting rod to rotate the shaft 9 from which rotatable means, power may be transmitted to perform work.

' Mounted on the crank shaft 9 is the sprocket wheel 10 connected by the sprocket chain 11 to the sprocket wheel 12 for driving the valve shaft 13 at the same angular velocity as the shaft 9. This shaft 13 carries a spiral gear 14 adjacent each cylindertoV mesh with a spiral gear'or toothed section 15 on each auxiliary rotatable non reciprocating cylinder 16, axially alined with each main cylinder 2 for two to one speed reduction in the rotation of the cylinders 16.

` The piston 5 has annular packing 17 adjacent its free end or remote from the crank shaft and has the annular packing 18 at the speeitaii of Letters' refait;

opposite; end.` Upon opposite sides; of the port6,the cylinder 5 is'provided with longitudinal packing or wipers 19l (Fig. 2)". Thereis, accordingly, effectiveY packing of the lateral port regions `of the piston 5 as to the lateral ports of lthe fixed cylinder 2.

.The piston 5 beyond thepacking 18 has the guide means or lugs 20 in a peripheral annular series on the side thereof remote from the port 6. These; guides 20 register to reciprocate in the" relatively` interfitting guide ways 21 extending longitudinally of the auxiliary or second c linder 16.` Accordingly, the rotation o` the shaft 9 is transmitted to rotateat one-half its speed the cylinder 16 and thereby give the piston one complete rotation in two of its recipro- In.` the throw ofthepistom away from the shaft 9, the lugs 20 travel in the guides 21 toward the end thereof. Alubricant supply,v preferably force feed, through the pipe 22, conveys fluid into the housing 1 surrounding the cylinder 16. This cylinder 16 has spiral ways 23 for Vconducting this fiuid in thoroughly lubricating its rotation. These ways 23 terminate in a top annular groove 24 into which ports 25 lead from the ends of the guideways 21. This serves not only to lubricate the piston in its reciprocation but operates as a fluid cushion to absorb concussion in the travel of the piston 5 to have its lugs 20 approach the ends of the ways 21.

The device of this disclosure is compact in features of assembly permitting effective heat regions. The actuation of the piston for rotation is by a device of simple structure with'few parts to complicate and these parts disposed for permitting close-assembly of the cylinders as to each other with maximum clearance for the connecting rod. This means a most advantageous stroke bore ratio. Considerable range is permissible in the disposing of the pair of ports for eachl cylinder as to the pair of ports forthe adjacent cylinder, the disclosure in Fig. 2 being in pairs with the auxiliary cylinders or sleeves 16 rotating toward each other as shown by the arrows. This permits a range for proportioning the manifold in various groupings for clearance as well as passage lengths giving the structure considerably exibility in de- Y 14, the toothed portions 15 of the adjacent sleeve 16 may be in mesh thereby permitting a most close grouping of the cylinders. Furthermore, the opposite pitching of the gears 14 tends to neutralize the thrusts of these auxiliary cylinder driving loads in the' shaft 13.

The effective driving of these port control sleeves may be 1n gang from a single pinion 141 say 'for each pair of cylinders in a four, or each three in a six, or other desired multiple grouping.

What is claimed and it is desired to secure by Letters Patent is:

1. A cylinder provided With lateral port means, a ported piston in said cylinder, rotatable means connected to said piston, and means for rotating said piston from said rotatable means including an auxiliary rotatable cylinder having a guide of an axial extent in excess of the piston travel, said piston being provided With a guide of less extent than the piston travel coacting With Gopies of this patent may be obtained for ve cents each, by addressing the Commissioner of latenta,V

the auxiliary cylinder guide for simultaneous rotation of the auxiliary cylinder and piston permitting relative reciprocation of the piston. j

2. An internal combustion motorv embodying a cylinder having a pair of ports, a relatively reciprocable piston in said cylinder, said piston having a single port, and a nonreciprocating cylindrical member for rotating the piston, said cylindrical member having' its cylindrical" axial extent as great as the piston travel reciprocations.

3. A reciprocable piston provided with a peripheral series of lugs adjacent one end, a cylinder in Which said piston is rotatable, a

vsecond cylinder rotatable With the piston and having Ways for the piston lugs,` said Ways terminating in ported pockets to provide fluid cushioning means for the piston. 4. A motor embodying a plurality of cylinders, rotatable pistons in said cylinders, toothed driving sleeves having spline coaction -With the pistons for rotating said .pistons, and Within the axial extent of one of Which sleeves one end of the piston is reciprocable, the teeth of said driving sleeves .on a pair of adjacentV cylinders meshing with each other.

In Witness whereof I aix my signature.
